Please don't try to give answer. Another way of writing that is x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x There's 5 rows and 9 columns. :) Now you can count the x, or just multiply it.

Tip for this in the future: Hold up 10 fingers and since you have 5 x 9 you put down the 5th finger on your left hand, and your are left with 4 on the left and 5 on the right put the two numbers beside each other and you get 45. You can do this trick with any number from 2 - 9 when multiplying by nine (:

Remember that multiplication is repeated addition: 5 x 9 = 9 + 9 + 9 + 9 + 9 = 45
